VIRUS REMOVAL

[Overkill]

I'm re-wording my question...

When working on a computer whether it's a friends or customers (if you have a business) how common is it for a virus to spread through your network?
Are there any ways to avoid this? maybe downloading signatures manually (on a clean PC) and transport them via usb to the infected computer so you don't risk infecting your own PC's on the network?

Disable all other computer from accessing the network?

I always use USB tools, boot CDs, etc... since most tools i have are portable.

the only time i connect my computer to a network , is to check if the supposed "infected" PC is blocked from internet by malwares or there is an issue wuth the router/network.

You can become infected quite easily by being on the same network with an infected machine, as Umbra stated, using a USB or rescue disk is the best solution. I personally update all my tools on my USB on my network, before going to someone else's that has an infected machine, or if they bring the computer to me, i will update before arrival, then shut down my network while working on their system.

Some routers like mine have a guest network option which can be setup to not connect to my other computers on my network. So the infected system is isolated from my other network systems.

I always boot the infected system into Windows safe Mode with Networking since most malware can not function in Windows Safe Mode and cleaning up the infected system is much easier. Scans are much faster as well in Windows Safe Mode.

Of coarse using a portable USB with tools is also a good option and saves a lot of time if you are in the business of removing malware.

Thanks.

Thanks all, once in a great while someone (usually a friend) needs their PC fixed and in the past i've connected to our network and luckily was never infected, but in the future I want to have a game plan without risking our pc's.
